I'm trying to update formats on MikTex 2.9 and receive the following error message:
miktex-makefmt.exe: Invalid control sequence. initexmf.EXE: The operation failed for some reason. initexmf.EXE: Data: C:\Program Files (x86)\MiKTeX 2.9\miktex\bin\miktex-makefmt.exe
Originally my problem is that when I try to compile I receive the message,
pdflatex.exe: Invalid control sequence.
I figured updating formats would fix this?
